Lightning radioactive

There are several manufacturers of either radioactive lightning or lightning dissipation systems. The predominant scientific belief, however, is that neither of these systems are any benefit over the conventional lightning protection system. Extensive studies have been performed recently on dissipation arrays which only serve to enhance what scientists dating back to Franklin over 200 years ago have said namely, that these arrays do no more than a conventional lightning rod and indeed probably do less. These studies have examined the historical, theoretical and experimental aspects of the arrays and have also investigated the arrays on site at several installations. [Pg.88]

The Poisson distribution arises when counting relatively seldom events such as lightning striking or radioactive processes as in the case of radiochemistry. [Pg.267]

The Heterotroph Hypothesis supposes that life on Earth evolved from heterotrophs, the first cells. According to this hypothesis, life began on Earth about 3.5 billion years ago. Scientists have shown that the basic molecules of life formed from lightning, ultraviolet light, and radioactivity. Overtime, these molecules became more complex and developed metabolic processes, thereby becoming heterotrophs. Heterotrophs could not produce their own food and fed off organic materials. However, they released carbon dioxide which allowed for the evolution of autotrophs, which could produce their own food through photosynthesis. The autotrophs and heterotrophs became the dominant life forms and evolved into the diverse forms of life we see today. [Pg.100]

Class IE electronic equipment within the APIOOO design is resistant to external electromagnetic interference and lightning. Even so, the complete loss of operability of electronic equipment within multiple cabinets would not compromise the control of core reactivity and the removal of heat from the core, or result in the uncontrolled dispersion of radioactivity or... [Pg.102]
